SP783 presents a couple of awkward challenges. First, the Queens are in a corner facing a Bishop at the other end of the long diagonal. On top of that, castling O-O-O looks to be more likely than O-O, but the King on the a-side will be under pressure from the enemy Bishops sitting on adjacent diagonals. How did the game proceed?
The second diagram shows the position after ten moves have been played by each side. Using the techniques that I introduced in Count the Developing Moves and Move Order in the Opening, let's summarize the development thus far.
White has made four Pawn moves, Black six (the a-Pawn has moved twice). Both players have castled O-O-O as expected. Of his remaining five moves, White has made three with the Knights to take control of d5, and two with the Queen to transfer it to c2. Of his remaining three moves, Black has taken two to get the Knights off the back rank and one to move the King to b8.
Neither player has moved a Bishop, but all four are already playing an active role in the game; moving the f- and g-Pawns was sufficient to activate them. Except for castling, neither player has moved a Rook, but all four are developed on central files, waiting for lines to open.
All things considered, White's position makes a better impression. The Queen and Knights are more active, while the d2-d4 break is a bigger threat than Black's pushing the a-Pawn. Although White went on to win, it would take a more profound analysis to determine if the seeds of victory were already present in the diagrammed position.

I'm not sure why Black resigned, but he must have been looking at material loss and had too much respect for his opponent's endgame skill to continue.
